expand (1-x^4)(-1+x+x^3)

expand

(1 - x^{4}) (- 1 + x + x^{3})

- 1 + x + x^{3} + x^{4} - x^{5} - x^{7}

Solution steps

(1 - x^{4}) (- 1 + x + x^{3})

Distribute parentheses

= 1 \cdot (- 1) + 1 \cdot x + 1 \cdot x^{3} - x^{4} (- 1) - x^{4} x - x^{4} x^{3}

Simplify

1 \cdot (- 1) + 1 \cdot x + 1 \cdot x^{3} - x^{4} (- 1) - x^{4} x - x^{4} x^{3} : - 1 + x + x^{3} + x^{4} - x^{5} - x^{7}

= - 1 + x + x^{3} + x^{4} - x^{5} - x^{7}

(2 x + 20 - 6 x^{2}) - (4 - 7 x^{2} + 12 x)

1 \frac{5}{12}

\frac{4 a ^{2}}{27 a}

\frac{x ^{2} + 4 x - 5}{x ^{2} - 2 x + 1}

3 x^{4} - 16 x^{2}
